some days ago we have temporarily disabled deduplication only under storage policy copy (Storage policy tab). Now, we want to allow deduplication again, however if we uncheck the option (temporarily disable deduplication) we see the message - Deduplication cannot be enabled on dependent copy when disabled on Storage Pool. And this is very strange. Under Storage Pool there have been no changes made, moreover, there is no option to uncheck temporarily disable deduplication (Storage Pool tab). Maybe, only one thing can be in play, the DDB is in Maintenance state because of verification in progress.
Storage Pool window - no option to switch disabled deduplication

Now, we know the solution. I have not enough rights to change this settings under Storage Pool tab - Advanced tab is for me gray
